Optimization of Liquid Oxygen Distribution Routes in Demand Conditions at Risk of Change After the Fleet Departs for the Agents
No full textThis study addresses vehicle routing to distribute liquid oxygen products from the factory to the agent by considering the risk of changes in liquid oxygen demand when the vehicle leaves the factory. Handling liquid oxygen inventory requires strict service, large storage areas and high storage costs. The uncertainty of liquid oxygen demand at the consumer level and inventory handling make agents change demand suddenly. This condition causes the quantity transferred to the agent not to match the amount of liquid oxygen transported by the fleet from the factory. If the change in demand decreases, the fleet must return the remaining liquid oxygen to the factory. Still, if the change increases, it will affect the vehicle's ability to meet the liquid quantity requested by the next agent. Furthermore, a vehicle routing model is developed that considers the possibility of changes in demand after the vehicle departs from the factory. The search for the optimal route solution for this model uses a guided local search algorithm. The study results showed an increase in vehicle transfer quantity of 4.23% from the previous route
Total Productive Maintenance Analysis of Wrapping Machine Line 4 through Overall Equipment Effectiveness and Six Big Losses at PT XY, Cirebon – West Java
No full textPT. XY is a company engaged in the food industry, namely instant noodles. The problem encountered atPT XY was that one of the machines that used in instant noodle production often stopped operating due toa breakdown. The machine that often experiences breakdowns is the Wrapping Line 4 machine, which is apackaging machine for cup noodle products. This results in a long machine downtime so that theproduction target is not achieved. One approach to addressing this problem is Total ProductiveMaintenance (TPM) which is measured through Overall Equipment Effectiveness (OEE) and Six BigLosses. This study aims to calculate the Overall Equipment Effectiveness (OEE) value, calculate the valueof the Six Big Losses factor and determine the root cause of the dominant problem of the Six Big Lossesfactor using a fishbone diagram. The calculation results show that the OEE value on the Wrapping Line 4is below the international standard, which is 78.03%. Dominant factors that cause machine effectivenesswas low are quality defect losses by 63,54% and reduce speed losses by 24,87%
